"I broke the belt," Streep told " Good Morning America" anchor Robin Roberts of the mishap to her long-sleeve, Oscar-gold gown by Lanvin when she celebrated Helland's win for his work transforming Streep into Margaret Thatcher in "The Iron Lady."

"I jumped up and the belt went [crack], so I had a wardrobe misfunction in the fourth award," she said.

While Streep was suffering from wardrobe distress, her fellow Oscar-winning actress, Best Supporting Actress Octavia Spencer, told Roberts that she was just happy she made it to the stage safely.

"I think they were happy that I didn't fall down these stairs," " The Help" star said of the standing ovation she received when her name was called and she made the treacherous walk from her seat to the stage.
